Item Build Description

Additional information on the items

Starting Items

Long Sword : Early Attack Damage (AD)
Ruby Crystal : Early Health Point (HP)
Boots of Speed : Early Movement Speed (MS)

Core Items

Black Cleaver : Synchronize well with Senna 's passive Absolution since it gives her bonus MS every time she Auto Attack. Of course, Trinity Force also does the same thing but Black Cleaver offers much more AD and HP and it also gives Senna Armor Reduction to enemy hit by any physical damage.
Boots of your choice

Going full AD build means you're very vulnerable since you're squishy. You can replace Youmuu's Ghostblade and Duskblade of Draktharr with situational items like Maw of Malmortius and Guardian Angel (depending on the situation). You still can run full AD but you need to pilot the champion properly.

Stormrazor : Decent for Senna since it helps her to kite better with the slow effect, as well as dealing more damage, crit and Attack Speed.
Enchant of your choice
Youmuu's Ghostblade : Gives Bonus MS when out of combat, also gives a decent Attack Speed when this item's passive is fully stacked (Spectral Haste). In short, more roam and more chase.
Duskblade of Draktharr : Most AD item, armor penetration as well. Good for damage, basically.
Infinity Edge : Most AD item, provide bonus crit damage. Good for damage, basically.

Defensive

Be flexible. You don't have to buy them in order. Just buy what you need first depending on the situation.

Iceborn Gauntlet : Good for slowing people = good for kiting. Having mana and Armor feels great as well no?
Enchant of your choice
Maw of Malmortius : No more worrying about enemy AP since you ain't gonna die any time soon against them.
Trinity Force : More Ability Haste, Attack speed, AD and MS when Auto Attacking
Guardian Angel : 2nd life feels pretty good I must say.

Situationals

Maw of Malmortius : Good against AP Assassins that want you dead. Also provide a fair amount of AD
Guardian Angel : Good against AD Assassins that want your head cut off. Also provide a fair amount of AD and gives you a 2nd life as well.

Boots

Boots of Swiftness : Good for kiting and slow reduction
Plated Steelcaps : Good against AD Champions especially Auto Attack Champions
Mercury's Treads : Good against AP Champions and Crowd Control (CC)

Summoner Spells

When to take which summoners

Flash

Even though Senna gains movement speed everytime she autos, she still can't go through walls and getting out of enemy's melee range.

Barrier

Shield that blocks a lot of damage for yourself. It can't be interrupted with anti-heal.

Exhaust

Due to its ability to reduce damage dealt and to slow the targeted enemy, this spell has become a spell for both defensive and offensive.

Heal

Can be countered by anti-heal. But it can also heal the most injured ally and provides movement speed for you and the healed ally.

Ghost

You have long range. With this, you can kite better. This will be super annoying for the enemy team to lock you down. Kite : Position yourself to a good position where the enemy can't touch you while attacking the enemy.

Ignite

Good if the enemy have healing champion(s) and lifestealers

Smite

It's not worth taking if you're going to lane since it reduces your EXP and gold gain from minions. Unless if you wanna try jungle Senna.

Combos

Learn how to maximize the champions potential

1st

Extended 1 Piercing Darkness

If you want to take this ability to another level :

Place a ward > Piercing Darkness . Your ward is also a targetable object that can extend your 1 Piercing Darkness .
Your 1 Piercing Darkness can also be extended upon hitting a minion, a monster, a tower and a champion (both enemy and ally).
Can only be extended by 1 target.

1st

3rd

Standard Trade

Your 1 Piercing Darkness resets your auto attack
You can get a free stack by attacking an enemy champion twice. (5 seconds cooldown)
Your 3 Curse Of The Black Mist is used to disengage if they're trying to punish you with an all-in combo. You'll never know. BUT it's not really necessary if the enemy team has not reach Level 5.

2nd

1st

3rd

Standard Early All-In

A very good combo that can be used either when you get a good gank from your jungler and when the enemy is low chance of survival.
Again, 3 Curse Of The Black Mist is used for disengage. It can also be used to give bonus movement speed for chasing the enemy down.

Ult

SENNA TIPS & TRICKS

Piercing Darkness and her Auto Attacks can't be blocked by Yasuo 's Wind Wall . But remember, your Ult Dawning Shadow can still be blocked by Wind Wall and Braum can still block everything with his 3 Unbreakable .
Attacking an enemy champion twice will drop a soul. (5 seconds cooldown btw)
Attacking a soul doesn't proc your energizer stack from Rapid Firecannon , Statikk Shiv , Stormrazor and Fleet Footwork . Therefore, you can proc your movement speed without using your energizer stack allowing you to trade with the enemy.
Even though souls only have 1 HP, Senna applies lifesteal and omnivamp on them as if she dealt a full Auto Attack and Ability damage
Senna 's passive [senna:passive] gives her 1 AD per stack, 25 range every 20 stacks, and 15% crit chance every 20 stacks. 35% of excessive Crit Chance will be converted to Lifesteal
Rapid Firecannon not only extend the range of your Auto Attacks but it also extend the range of your 1 Piercing Darkness .
1 Piercing Darkness that is extended by Rapid Firecannon will not proc your Rapid Firecannon 's passive until you hit an enemy champion. This means you can get a huge range on minion wave and and monsters. But it can still be proc by your Auto Attacks.
Senna 's 1 Piercing Darkness cancel your Auto Attack animation allowing you to use the Auto > Piercing Darkness > Auto combo (Standard Trade) in an instant.
Auto Attacks reset 1 seconds of your Piercing Darkness . Buying Runaan's Hurricane can proc 3 Auto Attacks.
Your Piercing Darkness can be extended on plants and proc the plants when it got hit.
Last Embrace is extremely slow. You can either do the [flash] > [senna:2] or wait till someone else CC the enemy team.
Curse Of The Black Mist makes you and your allies untargetable by Auto Attacks and on-hit abilities. Everyone inside the mist will also remains invincible as long as they're in the mist. This is a good surprise engage tool since the enemy team don't know who's inside and how many are there inside the mist.
You can treat Curse Of The Black Mist as a panic button you can press when an enemy engage happening.
Keep in mind you can't Auto Attacks or use Abilities while in the mist or else you'll just expose the allies inside including yourself.
Your Ult Dawning Shadow have a global range in which you can use to execute enemies and shield allies whenever they're teamfighting even when you're on the other side of the map.

Gameplay

Basically, you let your Support farm as if they're the ADC and you're the Support. Preferably, you want to pair up with damage Support like Seraphine , Lux , Annie , and Ashe .
